In the present embodiment:
Described chain-and-slat drying machine and far infrared drying oven can be buied in Qingdao Feng Lin Food Machinery Co., Ltd. or Shaoyang City strong wind drying equipment Co., Ltd.
Described rotary destilling tower is also referred to as rotating cone scapus (Spinning Cone Column, be called for short SCC), can science and technology (Tianjin) Co., Ltd of Ben section buy, it is a multistage mass transfer apparatus being formed by a series of alternately cones that fixing and rotation is blocked, the effective liquid-gas of a kind of uniqueness contact device, by the aromatic substance in material is extracted from tower body, condensation, be stored in desirable container, thereby collect natural essence and flavoring agent.SCC is a upright stainless steel pillar, and 30 cones that are arranged in parallel are up and down housed in post, one deck cone be fixed on can the newel of High Rotation Speed on, at interval of another layer be fixed on interior wall.In when operation, object adds from charge door above, and inert gas passes at the bottom of by post, and the fragrant composition that has after separation is taken out of by gas from top.The material adding declines along each layer of cone.Due to the moving hemicone High Rotation Speed of newel subband, liquid is formed very thin liquid level, and volatile inert gas that has fragrant composition to be made progress takes out of and constantly contact with liquid, exchange and concentrated, and is finally taken out of pillar and reclaims.The efficiency of SCC, than 5 times of high 4 ∽ of packed column, can be processed the material of various forms (containing very sticky).The separated time of SCC is very short, and operating temperature can be controlled between 120 degrees Celsius of 30 ∽.These advantages make it process thermal sensitivity have fragrant composition time, can keep the natural flavour mountaineous of them.
Described three grades of continuous reverse osmosis membrane separation systems, it is according to dehvery pump, booster pump, with the one-level membrane stack of internal circulation pump, with the secondary membrane stack of internal circulation pump, being linked in sequence with three grades of membrane stacks of internal circulation pump, and after one-level membrane stack, force (forcing) pump is installed, the feed pressure of two-stage membrane stack after improving, the water flux of rear two-stage membrane stack is increased, improve rejection, thereby both improved cycles of concentration, reduce again the loss of function and fragrance component in concentrate.
Described video disc thinfilm rotary evaporator can science and technology (Tianjin) Co., Ltd of Ben section be buied, changed to its subversiveness traditional evaporation pattern, it adopts the mode of rotation, the area of heating surface is rotated, thereby make to heat medium liquefaction laminar flow and the disappearance of product liquefaction laminar flow, heat and mass efficiency is provided greatly, thereby has greatly reduced required evaporating temperature and heat time, made the color and luster of product and loss of aroma minimum.
The organoleptic indicator of red date inspissated juice:
Reddish brown, color and luster homogeneous, thick liquid, reduces with Enrichment transparency, allows the insoluble plant particles of trace; Fragrance is natural, strong lasting, without other foreign gas; The fragrant and sweet nature of flavour.
The physics and chemistry sanitary index of red date inspissated juice:
Soluble solid (20 ℃, compound microcapsule), 30.0 ± 2.0 Brix; Total number of bacteria ,≤10 cfu/g; Coliform ,≤3.0 MPN/g; Mould and saccharomycete ,≤10 cfu/g; Pathogenic bacteria (salmonella, Shigella, staphylococcus aureus), must not detect.
